It is understood that radicals of formula (f) wherein R₁₁ stands forhydrogen, as well as the radical of formula (h) may also exist undertheir tautomeric enol, respectively thienol, forms. Such enol andthienol forms, although not explicitely indicated in the abovestructures, are naturally intended to be within the scope of formula(I).

As used herein, the term "lower alkyl" denotes straight and branchchained hydrocarbon radicals having from 1 to 6 carbon atoms, such as,for example, methyl, ethyl, 1-methylethyl, 1,1-dimethylethyl, propyl,butyl, pentyl, hexyl and the like; and the term "halo" is generic tohalogens of atomic weight less than 127, i.e. fluoro, chloro, bromo andiodo.

Preferred compounds within the scope of formula (I) are those wherein Qis CH and wherein the Y substituent is located at the position of thebenzene nucleus which is para to the dioxolanylmethoxy group.Particularly preferred are those compounds wherein Ar represents ahalophenyl or di-halophenyl radical, the most preferred being2,4-dichlorophenyl.

In order to simplify the structural representation of compounds (I) andof certain starting materials and intermediates used in the preparationthereof, the 2-Ar-2-(1H-imidazol-1-ylmethyl or1H-1,2,4-triazol-1-ylmethyl)-1,3-dioxolan-4-yl group wherein Ar is aspreviously defined, will hereafter be represented by the symbol D:##STR10##

The compounds of formula (I) wherein Y is as previously defined butother than a radical of the formula (f) wherein R₁₁ is hydrogen andother than a radical of formula (h), said Y being represented by Y₁ andsaid compounds by the formula (I-a), can be prepared by the reaction ofan appropriate reactive ester of the formula (II) with an appropriatelysubstituted phenol of formula (III). ##STR11## in formula (II), W hasthe meaning of a reactive ester residue such as, for example, halo,methylsulfonyloxy, 4-methylphenylsulfonyloxy and the like. The reactionof (II) with (III) is carried out under art-known conditions ofperforming O-alkylations with reactive esters. The reaction is generallycarried out in an appropriate reaction-inert organic solvent such as,for example, N,N-dimethylformamide, N,N-dimethylacetamide,hexamethylphosphoric triamide, dimethylsulfoxide, 4-methyl-2-pentanoneand the like, optionally in admixture with other reaction inert solventssuch as, for example, aromatic hydrocarbons, e.g., benzene,methylbenzene, dimethylbenzene and the like. Further it is advantageousto add to the reaction mixture an appropriate base such as, for example,an alkali metal hydride or carbonate, in order to enhance the rate ofthe reaction. Otherwise it may be advantageous to first convert thesubstituted phenol (III) into a metal salt thereof, preferably thesodium salt, in the usual manner, e.g., by the reaction of (III) withmetal bases such as sodium hydride, sodium hydroxide and the like, andto use thereafter said metal salt in the reaction with (II). Somewhatelevated temperatures are appropriate to enhance the reaction rate andmost preferably the reaction is carried out at from about 80° C. toabout 130° C.

Compounds of formula (I) wherein Y has the formula (c) wherein R₄ and R₅are as previously defined and R₃ is hydrogen, lower alkylthio, loweralkylsulfinyl or lower alkylsulfonyl, or, the formula (e), (f), (g) or(h), said Y being represented by Y₂ and said compounds by the formula(I-b), can also be prepared by cyclizing an appropriate intermediate(IV) wherein A is an amino group or a derivative thereof, with anappropriate cyclizing agent, and, if desired, introducing suitablesubstituents into the thus obtained heterocyclic compounds. ##STR12##

The nature of A in formula (IV), as well as the nature of the cyclizingagent to be used in the cyclization step, depend upon the meaning of Y₂in the desired compounds (I-b) as will be explained hereafter.

Compounds of formula (I-b) wherein Y₂ has the formula (c) wherein R₄ andR₅ have the previously indicated meaning and R₃ is hydrogen, loweralkylthio, lower alkylsulfinyl or lower alkylsulfonyl, said R₃ beingrepresented by R₃ ' and said compounds by (I-b-l), can be derived froman appropriate isothiocyanate of the formula (IV-a) by cyclizing thelatter with an appropriate aminoethanone or aminoacetaldehyde of theformula (V) and thereafter introducing appropriate substituents into thethus obtained 1H-imidazole-2-thiol of formula (VI) following art-knownprocedures ##STR13##

The reaction of (IV-a) with (V) to produce (VI) is conveniently carriedout by stirring, preferably under heating, the reactants together in asuitable organic solvent, such as a lower alkanol, e.g. 2-propanol, inthe presence of an appropriate base such as, for example, an alkali orearth alkaline metal carbonate or hydrogen carbonate. The introductionof the desired R₃ ' substituents into (VI) can be accomplished bygenerally known procedures such as the following.

When R₃ ' stands for hydrogen the compounds (I-b-1) are easily obtainedby desulfurating (VI) in the usual manner, e.g., by treating the latterwith Raney-nickel or with diluted nitric acid. When R₃ ' stands forlower alkylthio the compounds (I-b-1) can be obtained by subjecting (VI)to a standard S-alkylation with a suitable reactive ester of the formula(VII)

    (lower alkyl)-W                                            (VII)

wherein W is as previously defined, or, with a di(lower alkyl) sulfate.When R₃ ' is a lower alkylsulfinyl or lower alkylsulfonyl group thecompounds (I-b-1) are obtained by subjecting the corresponding compoundswherein R₃ ' is lower alkylthio to an oxidation reaction with andappropriate oxidizing agent. Appropriate oxidizing agents to be usedtherefore include, for example, hydrogen peroxide, optionallysubstituted benzeneperoxoic acids, e.g. 3-chlorobenzeneperoxoic acid,and permanganate salts such as potassium permanganate. The degree ofoxidation, i.e. respectively to the sulfoxide or sulfone level, isdetermined by the ratio of the reagents. When sulfoxides are to beprepared about 2 equivalents of the oxidizing agent are to be used permole of sulfide while at least 4 equivalents are necessary to producesulfones. Oxidations with hydrogen peroxide and permanganate salts arepreferably carried out in acidic aqueous medium while oxidations withbenzeneperoxoic acids are preferably conducted in an appropriatereaction-inert organic solvent, e.g. a halogenated hydrocarbon such asdichloromethane.

Compounds of formula (I-b) wherein Y₂ has the formula (f) wherein R₁₁ ishydrogen, (I-b-2), are conveniently derived from an appropriateintermediate of the formula (IV-b) wherein X is as previously defined,using as a cyclizing agent an appropriate alkanimidamide of the formula(VIII) wherein R₁₀ has the previously indicated meaning, or an acidaddition salt thereof. ##STR14##

The cyclization reaction may be carried out according to methodologiesknown in the art, for example, by mixing and melting the reactantstogether, if desired in the presence of an appropriate reaction-inertorganic liquid having a relatively high boiling point such as, forexample, 1,1'-oxybis(2-methoxyethane).

Compounds of formula (I-b) wherein Y₂ has the formula (f) wherein X is Oand R₁₁ is lower alkyl, (I-b-4), can be prepared by N-alkylating acompound of the formula (I-b-2) wherein X stands for O, (I-b-3), with anappropriate reactive ester of formula (VII). ##STR15##

Said N-alkylation may be carried out in the usual manner, e.g. bystirring the reactants together, preferably at somewhat elevatedtemperatures in an appropriate organic solvent such as, for example,dimethylsulfoxide, in the presence of an appropriate base such as, forexample, an alkali metal hydride or carbonate.

The compounds of formula (I-b) wherein Y₂ has the formula (e), (I-b-6),can be prepared by introducing R₈ into an appropriate compound (I-b-2)wherein X stands for S and R₁₀ has the meaning of R₉ as previouslydefined, said starting compounds being represented by the formula(I-b-5). ##STR16##

Compounds of the formula (I-b-6) wherein R₈ is hydrogen, loweralkylthio, lower alkylsulfinyl or lower alkylsulfonyl are derived from(I-b-5) using similar procedures as described hereinbefore for thepreparation of compounds (I-b-1) starting from (VI). Those compounds offormula (I-b-6) wherein R₈ is lower alkyloxy can be derived from thecorresponding lower alkylsulfonyl substituted compounds by reacting thelatter with an appropriate lower alkanol to replace the loweralkylsulfonyl group by a lower alkyloxy group. The reaction ispreferably conducted at slightly elevated temperatures in an appropriaterelatively polar, organic solvent, such as dimethylsulfoxide, in thepresence of a strong metal base such as, for example, an alkali or earthalkaline metal hydride.

Compounds of formula (I-b) wherein Y₂ is a radical of formula (g),(I-b-7), can be prepared by the reaction of an intermediate of formula(IV) wherein A stands for an amino group, (IV-c), with an azide,preferably an alkali metal azide, e.g. sodium azide, and an appropriate1,1',1"-methylidynetris(oxy)tris(lower alkane) of formula (IX) in anappropriate acidic medium, e.g. acetic acid, preferably under heating.##STR17##

Compounds of formula (I-b) wherein Y₂ has the formula (h), (I-b-8), canbe obtained by the reaction of an isothiocyanate of formula (IV-a) withan appropriate azide, preferably sodium azide, in an appropriate organicsolvent, e.g. a lower alkanol such as methanol, ethanol, 2-propanol andthe like in the presence of alkali. ##STR18##

Said cyclization reaction may also be carried out by stirring (IV-a)with the azide in the presence of an appropriate quaternary ammoniumsalt, preferably N,N,N-triethylbenzenemethanaminium chloride, in asuitable solvent system such as, for example, water preferably inadmixture with an appropriate organic solvent such as, for example,1,4-dioxane, to better solubilize the reactants.

The imidazole derivatives of formula (I), obtained in base form in theforegoing preparations, may be converted to their therapeutically usefulacid addition salts by reaction with an appropriate acid, as, forexample, an inorganic acid such as hydrohalic acid, i.e., hydrochloric,hydrobromic or hydroiodic acid; sulfuric, nitric or thiocyanic acid; aphosphoric acid; an organic acid such as acetic, propanoic,hydroxyacetic, 2-hydroxypropanoic, 2-oxopropanoic, ethanedioic,propanedioic, 1,4-butanedioic, (Z)-2-butenedioic, (E)-2-butenedioic,2-hydroxy-1,4-butanedioic, 2,3-dihydroxy-1,4-butanedioic,2-hydroxy-1,2,3-propanetricarboxylic, benzoic, 3-phenyl-2-propenoic,α-hydroxybenzeneacetic, methanesulfonic, ethanesulfonic,2-hydroxyethanesulfonic, 4-methylbenzenesulfonic, 2-hydroxybenzoic,4-amino-2-hydroxybenzoic, 2-phenoxybenzoic or 2-acetyloxybenzoic acid.The salts are in turn converted to the corresponding free bases in theusual manner, e.g., by reaction with alkali such as sodium or potassiumhydroxide.

A number of the intermediates and starting materials used in theforegoing preparations are known compounds, others may be preparedaccording to art-known methodologies of preparing similar compounds andsome of them are novel and consequently their preparation will bedescribed hereafter.

Starting materials of formula (III) can in general be derived from thecorresponding methoxy-substituted compounds of formula (X) by convertingthe methoxy group of the latter into a hydroxy group by acid hydrolysisusing a strong non-oxidizing mineral acid, such as, for example,hydrobromic acid in acetic acid. ##STR19##

The intermediates of formula (X), used as starting materials herein canbe obtained by a variety of methods, depending on the nature of Y₁ insaid formula (X).

Intermediates of formula (X) wherein Y₁ has the formula (a), (b), (c) or(d), said Y₁ being represented by Y₁ ' and said intermediates by (X-a),can conventiently be prepared by the reaction of an appropriatehalo-methoxybenzene of formula (XI) with an appropriate azole of formula(XII). ##STR20##

The reaction of (XI) with (XII) is carried out according to artknownprocedures, e.g., by stirring the reactants together for from severalhours to several days in an appropriate organic solvent such as, forexample, N,N-dimethylformamide, N,N-dimethylacetamide,hexamethylphosphoric triamide, dimethylsulfoxide and the like, mostpreferably in the presence of an appropriate copper (I) salt, e.g. thechloride or the bromide, to enhance the reaction rate.

Those intermediates of formula (X) wherein Y₁ has the formula (a) aswell as the corresponding phenols of formula (III) can also be preparedaccording to the method described in Ber. 95, 2270 (1962).

Intermediates of formula (X) wherein Y₁ has the formula (b), (X-b), mayalso be prepared by the reaction of an appropriate(methoxyphenyl)hydrazine of formula (XIII), which is usually employed inthe form of an acid addition salt, with an appropriate dione of formula(XIV) wherein R₁ and R₂ are as previously defined. ##STR21##

The reaction of (XIII) with (XIV) is conveniently carried out bystirring and refluxing the reactants together in an appropriate organicsolvent, e.g. a lower alkanoly such as ethanol, preferably but notnecessarily in the presence of an appropriate base such as, for example,an alkali metal carbonate, e.g., potassium carbonate. When R₁ stands forhydrogen, the adjacent carbonyl group of (XIV) is preferably ketalizedprior to reacting said (XIV) with (XIII) in order to obtain a pyrazolederivative wherein R₂ is unambigously located at the 5-position.Mixtures of position isomers which can otherwise be obtained when usingunketalized aldehydes or ketones of formula (XIV) may be subjected tostandard isolation and purification procedures to separate the pureconstituents from each other.

Intermediates of formula (X) wherein Y₁ stands for a radical of theformula (C) wherein R₃ has the meaning of R₃ -40 as previously defined,(X-c), can also be derived from an appropriate isothiocyanate of theformula (XV) by cyclizing the latter with an appropriate aminoethanoneof the formula (V) and thereafter introducing the desired R₃'-substituents into the thus obtained (XVI) following similar proceduresas previously described herein for the preparation of compounds (I-b-1)starting from (IV-a) ##STR22##

Intermediates of formula (X) wherein Y₁ stands for a radical of formula(d), (X-d), can also be prepared starting from a appropriate1-(methoxyphenyl)-1H-1,2,4-triazole-3-thiol of formula (XVII) bydesulfurating or S-alkylating the latter in the usual manner to obtain(X-d) wherein R₆ is hydrogen or lower alkylthio. ##STR23##

The 1H-1,2,4-triazole-3-thiols of formula (XVII) used as startingmaterials herein can be derived from an appropriate2-(methoxyphenyl)hydrazinecarbothioamide of formula (XVIII) by cyclizingthe latter with an appropriate carboxylic acid of the formula ##STR24##or a functional derivative thereof, such as, for example, an acylhalide, an ester, or preferably an imidamide of the formula ##STR25##The reaction is conveniently carried out by stirring and heating thereactants together in an appropriate organic solvent, e.g. a loweralkanol such as, for example, 2-propanol, butanol and the like.

Alternatively the same compounds (XVII) can be obtained by firstacylating (XVIII) with an appropriate anhydride (XX) or acyl halide(XIX-b) derived from an acid of formula (XIX), to obtain an intermediateof formula (XXI), and, thereafter cyclizing the latter by stirring andheating (XXI) in alcoholic alkali. The foregoing reaction areschematically represented as follows: ##STR26##

Still another method of preparing the compounds of formula (XVII) is byreacting a hydrazine hydrochloride of formula (XIII-a) with an acylisothiocyanate of formula (XXII) in N,N-diethylethanamine, washing thereaction mixture with water, evaporating off the solvent and thereafterstirring and heating the residue in a mixture of dichloromethane andethanol in the presence of alkali. ##STR27##

Intermediates of formula (X) wherein Y₁ is a radical of the formula (e)or (f) can easily be derived from aN-(methoxyphenyl)hydrazinecarboxamide or carbothioamide of the formula##STR28## by the application of similar procedures as previouslydescribed herein for the preparation of compounds (I-b-2), (I-b-4) and(I-b-6) starting from (IV-b).

Intermediates of formula (X) wherein Y₁ is a radical of formula (g) canbe derived from a methoxybenzenamine of the formula ##STR29## followingthe procedures described herein for the preparation of compounds (I-b-7)starting from (IV-c).

The precursor materials of the formulae (XIII), (XV) and (XXIV) hereinare generally known and may be prepared following methods described inthe literature.

The precursor materials of formula (XVIII) are easily prepared by thereaction of the corresponding hydrazine hydrochloride with potassiumisothiocyanate, according to the procedure described in C.A., 59 8651 b(1963) wherein the 4-substitued analog is specifically described.

The precursor materials of formula (XXIII) wherein X stands for S,(XXIII-a), are described in C.A., 18, 378⁸ (1924); C.A., 47, 3342i(1953); C.A., 56, P 3681a (1962); C.A., 51, 12016h (1957); and J. Am.Chem Soc., 70, 3439 (1948).

The precursor materials of formula (XXIII) wherein X stands for O,(XXIII-b), are easily obtained by the reaction of a phenyl(methoxyphenyl)carbamate (XXV) with hydrazine hydrate. ##STR30##

The carbamates of formula (XXV) are conveniently prepared by thereaction of a benzenamine of formula (XXIV) with phenylcarbonochloridate. The compound of formula (XXIII-b) wherein the methoxygroup is located at the para-position is described in C.A., 31, 3891⁸(1937).

Starting materials of formula (II) wherein Q stands for CH and methodsof preparing the same are described in Belg. Pat. No. 837,831. Ingeneral reactive esters of formula (II) can be prepared along thefollowing sequence of reactions.

An appropriate 1-Ar-2-bromoethanone of formula (XXVI) is subjected to aketalization reaction with 1,2,3-propanetriol following methodologiesanalogous to those described in Synthesis, 1974 (I), 23.

In a preferred manner of carrying out the reaction both reactants arerefluxed together for several hours with azeotropic water removal in anappropriate organic solvent, preferably in the presence of a simplealcohol, such as, for example, ethanol, propanol, butanol, pentanol andthe like, and in the presence of an appropriate strong acid such as4-methylbenzenesulfonic acid. suitable organic solvents are, forexample, aromatic hydrocarbons, such as benzene, methylbenzene,dimethylbenzene and the like and saturated hydrocarbons, such ascyclohexane.

The thus obtained dioxolane (XXVII) is then reacted with benzoylchloride to obtain a benzoate of the formula (XXVIII) and the latter issubsequently reacted with 1H-imidazole or 1H-1,2,4-triazole. Saidreaction is preferably carried out by stirring and heating the reactantstogether in a suitable organic solvent, e.g. N,N-dimethylformamide, inthe presence of an appropriate strong metal base, e.g. sodiummethanolate to obtain an intermediate of the formula (XXIX). The desiredreactive esters of formula (II) are then conveniently prepared by firsthydrolyzing (XXIX) in alkaline medium and thereafter converting thehydroxy group of the thus obtained (XXX) into a reactive ester thereofaccording to methodologies generally known in the art. For example,methanesulfonates and 4-methylbenzenesulfonates are convenientlyprepared by the reaction of the alcohol with methanesulfonyl chloride or4-methylbenzenesulfonyl chloride and halides may be prepared by thereaction of the alcohol with an appropriate halogenating agent such as,for example, sulfuryl chloride, phosphor pentachloride, phosphorpentabromide, phosphoryl chloride and the like. When the reactive esteris an iodide, it is preferably prepared from the corresponding chlorideor bromide by the replacement of that halogen with oidine.

The foregoing reactions may be illustrated as follows: ##STR31##

Intermediate of formula (IV) may be obtained along the followingreaction sequence.

An appropriate reactive ester of the formula (II) is reacted in theusual manner with a N-(hydroxyphenyl)acetamide, (XXXI), to obtain anintermediate of formula (XXXII), the amide group of which is subjectedto alkaline hydrolysis, e.g., with alkanolic alkali, to obtain thecorresponding amine, (IV-c).

Intermediates of formula (IV) wherein A stands for isothiocyanato,(IV-a), are easily derived therefrom by the application of art-knownmethods of preparing isothiocyanates from amines, e.g., by the reactionof (IV-c) with carbon disulfide andN,N-methanetetraylbis(cyclohexanamine) in pyridine.

Intermediates (IV) wherein A stands for a hydrazinecarbothioamide group,(IV-b-1), can be derived from (IV-a) by the reaction thereof withhydrazine hydrate.

Intermediates (IV) wherein A stands for a hydrazinecarboxamide group,(IV-b-2), can be prepared by first converting (IV-c) into a phenylcarbamate (XXXIII) by the reaction of the former with phenylcarbonochloridate and subsequent reaction of said (XXXIII) withhydrazine hydrate.

The foregoing reactions are schematically illustrated hereafter.##STR32##

The intermediates of formulae (IV-b-1) and (IV-b-2) and thestereochemically isomeric forms thereof are deemed to be novel, and, asuseful intermediates herein they constitute an additional feature ofthis invention. The intermediates of formulae (IV-a), (XXXII), (IV-c)and (XXXIII) are also deemed to be novel and, apart from their utilityas intermediates herein, they possess themselves antifungal andantibacterial properties, and, as such they are described and claimed inour U.S. Pat. Application Ser. No. 764,263 filed Jan. 31, 1977, nowabandoned and subsequently filed as a continuation-in-part applicationSer. No. 853,728 filed Nov. 21, 1977, now U.S. Pat. Nol 4,144,346.

From formula (I) it is evident that the compounds of this invention haveat least two asymmetric carbon atoms in their structures, namely thoselocated in the 2- and 4-position of the dioxolane nucleus, andconsequently they can exist under different stereochemically isomericforms. The stereochemically isomeric forms of (I) and thepharmaceutically acceptable acid addition salts thereof are intended tobe within the scope of this invention.

The diastereomeric racemates of (I), denoted as cis and trans formsrespectively, according to the rules described in C.A., 76, Index Guide,Section IV, p. 85 (1972), may be obtained separately by conventionalmethods. Appropriate methods which may advantageously be employedtherefore include, for example, selective crystallization andchromatographic separation, e.g. column-chromatography.

Since the stereochemical configuration is already fixed in theintermediates (II) and (IV) it is also possible to separate cis andtrans forms at this or even an earlier stage, whereupon thecorresponding forms of (I) may be derived therefrom in the previouslyindicated manner. The separation of cis and trans forms of suchintermediates may be performed by conventional methods as describedhereabove for the separation of cis and and trans forms of the compounds(I).

It is evident that the cis and trans diastereomeric racemates may befurther resolved into their optical isomers, cis(+), cis(-), trans(+)and trans(-) by the application of methodologies known to those skilledin the art.

The compounds of formula (I) and the pharmaceutically acceptable acidaddition salts thereof are useful agents in combatting fungi andbacteria. For example, said compounds and acid addition salts thereofwere found to be highly active against a wide variety of fungi such as,for example, Microsporum canis, Ctenomyces mentagrophytes, Trichophytonrubrum, Phialophora verrucosa, Cryptococcus neoformans, Candidatropicalis, Candida albicans, Mucor species, Aspergillus fumigatus,Sporotrichum schenckii and Saprolegnia species, and against bacteriasuch as, for example, Erysipelotrix insidiosa, Staphylococci such asStaphylococcus hemolyticus and Streptococci such as Streptococcuspyogenes. In view of their potent, local as well as systemic,antimicrobial activity the compounds of this invention constitute usefultools for the destruction or prevention of the growth of fungi andbacteria and more particularly they can effectively be used in thetreatment of subjects suffering from such microorganism.

The strong antimicrobial activity of the compounds (I) is clearlyevidenced by the data obtained in the following experiments, which datais only given to illustrate the useful antimicrobial properties of allthe compounds (I) and not to limit the invention either with respect tothe scope of susceptible microorganisms nor with respect to the scope offormula (I).

EXPERIMENT A Activity of compounds (I) against vaginal candidosis inrats.

Female Wistar rats of ±100 g body weight were used. They wereovariectomized and hysterectomized and after three weeks of recovery,100 μg of oestradiol undecylate in sesame oil was given subcutaneouslyonce a week for 3 consecutive weeks. The thus induced pseudooestrus wascontrolled by microscopic examination of vaginal smears. Food and waterwere left available ad libitum.

The rats were infected intravaginally with 8.10⁵ cells of Candidaalbicans, grown on Sabouraud broth for 48 hours at 37° C. and dilutedwith saline. The date of infection varied from day +25 to day +32 aftersurgical intervention, depending on the appearance of signs of inducedpseudo-oestrus.

The drugs under investigation were administered orally once a day fortwo days starting from the day of infection. For each experiment therewere placebo treated controls. The results were assessed by takingvaginal smears with sterile swabs on several days after the infection.The swabs were put into Sabouraud broth in petri-dishes and incubatedfor 48 hours at 37° C. If no growth of Candida albicans occured, i.e.,when the animals were negative at the end of the experiment, this wasdue to drug administration because it never happened in placebo treatedcontrols.

The tables I and II below give the lowest oral dose of the drug underinvestigation which was found active at the 14th day after infection.

EXPERIMENT B Activity of compounds (I) against crop candidosis inturkeys.

Turkeys of 14 days old were infected in the crop with 4.10⁶ Candidaalbicans cells, grown on Sabouraud broth for 48 hours at 37° C. anddiluted with saline. The volume of the inoculum was 1 ml. The drug underinvestigation were premixed in 500 mg of lacton and thereafter admixedin 1000 g of meal without any additives. The concentration of the drugunder investigation in the meal was expressed in mg/kg.

The animals were given the medicated feed for 13 consecutive daysstarting on the day of infection. At the end of the experiment allanimals were sacrificed. At autopsy the crops were removed, emptied andgrinded in an ultra-turrax mixer in 15 ml of sterile saline. Colonycounting was done on Sabourand agar and the results given in Tables Iand II represent the ED₅₀, i.e., the dose of the drug whereby the cropsof 50% of the animals were completely negative for Candida albicans.
